sin y so provided with circular openings' to loosely rubber -tire'a'ndexert an outward pressure threaded endsproieting outwardl the wheelfolly. Upon the rectangua'r porthereon. After the tire' has been securedupon my improved rim in this manner, the

rim is inserted from the outside of the wheel over the metal band 7,which is arranged upon the wheel felly, until the rim sections Y abutagainst the outstanding Vflange 8 Von the inner edge' of said follyband. The band 7 and the rim upon which the rubber tireis mounted,arethensecured upon the wheel Zfelly by means of a series ofbolts,indicated at 23. These bolts lextendtransversely through theqfellyof the wheel and. are4 provided with rectangular portions to preventtheir turning movement. Theextremities of thebolts arecylind'rically'formedf and screwthreaded', as indicated at-23', said from tions ofthese bolts, the clamping plates or y lugs 24 are arranged adjacent tothe bolt heads.' These plates engage upon the inner 'face vofthe wheelfelly and upon the {iange 8 oith'eannular felly band 7. It will beapparent' that the clamping plates or lugs prevented, by the rectangularportions o' the bolts, from turning thereon. Similar clamping plates 25are also arranged upon the louter cylindrical ends 23 of theseveralbolts, said'latter plates being receivesaid bolts. Nutsj26: arethreaded upon the end s'23 'ofthe bolts to securely clamp the latterplates 25 against the outer lface of the wheel felly, the edge of theband. 7 and the outerva'nges 'of the several rim sections 9. Thus, itwill be apparent that all ofthe parts are securely held against Alateralshifting movement with respect to each other or with. relation to thewheel upon which they. vare mounted. The metal band 7 is provided'withrecesses or seats in .its body, as shown at 27 and 27', to receive thelatchiiig 'device above referred to', and the hinges 11, respectively.By the provision of these s'eats in the metal band, tiirn. ing orcircumferential movement of the demountable rini .upon said band, isprevented; and Wear, consequently upon friction betweew these parts isthiis eiiminated.

From the foregoing description, taken .in connection with theaccompanying drawing, it is thought that the construction, manner ofuse, and several advantigesof my invention, will be clearly aid'fiillyunderstood.'-y

Tlie device, as a whole,''is of very simple construction, and byproviding the rin'i'in a series of relatively movable sections, it'

will be appreciated that the same is o'f great convenience in practicaluse, infthat `it admits of a number 'of the rims being compactly foldedand arranged in a comparatively small space in the vehicle body.` My

' signatii're in the ...improved tire rim 'may be very easily and iquickly arranged in position for use and the l tire engaged thereon, and.by the Vprovision of the latching device above described, the

several sections will be positively against any relative movement afterthe tire liasi been applied to the wheel.

heldA While I have illustrated a particular form of the hingedlyconnected rim sections in the accompanying drawing, it is to beunderstood, of course, that the form of these sections may be variouslyaltered to adapt the device for use in connection with pneumatic orsolid rubber tires of any 'desired cross-sectional configuration. Thedevice is4 also susceptible of a greatmany modifications in the form,proportion, and arrangefe nient of the several elements employed,and-

I,-thercfore, reserve the privilege of resorting'4 to all sii'chlegitimate changes as mayA be fairly embodied -within the spirit andmetal -rim sections adapted for relative' movement whereby the saine maybe enlatchV lever pivotallyl mounted upon the exvtremity of one section,a keeper secured upoii'the extremity ofthe opposed iiin s'ecf -tion' andprovided with va curvedlip to receive one end of said lever, said leverbeing provided adjacent to 'its latter end and between the same and itspivot with an opento the latter rim section for engagement in saidopening to positively hold the rim'sections against relativecircumferential movement.

2. A demountable rim for wheel tires in- Acludiiiga plurality ofhingedlyconnected rim sections .adapted to be engaged against f gagedagainst the inner side of the tire, a

y lim ing, and an inwardly projecting stud fixed l f the inner face ofthe wheeltire, a'lateli lever pivotally mounted upon the extremity ofone of the riin sections and having a ,cylindrically formed terminal, akeeper member fixed to the extremity of the opposed rim section andprovided with a curved lip to' receive the cylindrical extremity of thelatch lever, and additional means on the Vlatter rim section'tocoperatie with the lever and n positively prevent relativecircumferential movement of the rim sections.
